Looking to turn two HamShields or HamShield: LoRa Editions into a cross band repeater? This is the module for you.

The VHF/UHF Splitter-Combiner can isolate a VHF and UHF transmitter and make use of the same antenna.

Each radio path has about 40dB of isolation, which makes it safe to use across our entire product line. SWR is <1.5.

From our testing using the Wideband Power Meter, with a 1 watt 440MHz transmitter plugged into the UHF side, and a whip antenna plugged directly into the combiner's output, we see about 37 to 38dB of isolation. The antenna 4" away is probably to blame for the 2-3 dB isolation discrepancy.

Plug the VHF radio into V, and the UHF radio into U. Connect the output to an antenna.
